LOUIS NEES, OF MINNEAPOLIS, MINNESOTA, .ASSIGNOR OF ONE-HALF TO ROBERTJ.

CHENEY, OF MINNEAPOLIS, MINNESOTA.

WINDOW FRAME AND SASHES.

.To all tviwmit may concern:

Be it known that I, Louis Nans, a citizen of the United. States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and `useful Improvements in WindowFrames and vSashes; and I do hereby declare the `following' to be afull, clear, and exact description of the invention, lsuch as willenable others skilled in the art to which it appertains to make and usethe same.`

My invention relates to improvements in window frames and sashes, andhas for its object to provide means to temporarily support vertically`movable window sashes for horizontal swinging movement, whereby saidsashes may be swung into a room, so that the same may be washed on theoutside, painted or repaired. y

To the above end, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings,

Figure 1 is an inside elevation of a window frame and `upper and lowervertical sliding window sashes having the invention incorporatedtherein, some parts being broken away, other partsbeing shown invertical section, and still other parts being shown indifferentpositions by means of broken lines;

Fig. 2 is a vertical section taken on the line 2 2 ofFig. 1;

Fig. 3 is a `fragmentary plan view showing the window sashesswunghorizontally into the room with some parts sectioned on the line3-3 of Fig. 1;

Fig. 4t isa view corresponding to' Fig. 1, but on a reduced scale andwith the window sashes positioned as shown in Fig. 8; and

Fig 5 is a fragmentary inside elevation, with some parts sectioned onthe line 5-5 of Fig.\2, on an enlarged scale, and showing the movablesection of the window frame adjusted to permit the window sashes toclear the opposite" window stops and be swung horizontally.

The numeral 6` indicates a window frame Specification of Letters Patent.Pgfbntdl Jun@ 225, 191%, Application filed J une 15, 1917. Serial No.174,849.

having inner, outer and intermediate sash stops 7, 8 and 9,respectively, and alsohaving ateach side a weight-box 1 0. An upperwindow sash 11 and a lower window sash. 12 are mounted in the windowframe 6 for vertical sliding movement, the former between the outer andintermediate sash stops 8 and 9, and the latter between the inner andintermediate sash stops 7 and 9. Sash cords 13 and weights 141 areprovided for counterbalancing the window sashes 11 and 12. r1`he sashcords 13 are secured to the window sashes 11 and 12 in the customarymanner, but it is important to note that the sash cords 13, at theright, with respect to Fig. L1, are attached directly to the windowframe 6, and the respective weights 14 are provided with pulleys 15,which travel on the intermediate portions of said cord within therespective weight-box 10. `The purpose of thus attaching-said sash cords13 to the window frame 6 and connecting theV weights thereto is tosecure an increase in length of said sash cords, for a purpose whichwill presently appear.

The left hand side member of the 'window frame 6 is provided with anintermediate section 16, located between the inner and outer stops 7 and8, respectively, and arranged to be moved horizontally into the adjacentweight-box 10. rlihe ends of the `window frame section 16 have beveledendow frame 6 and is secured for common movement therewith.

Embracing the sectional sash stop 9 and overlapping the joints therein,are upper and lower channel bars 17 that are rigidly secured to the endmember of said sash stop 9. Extending transversely through theintermediate web of Ieach channel bar 17, is a screw 18 having in itshead an annular groove 19in which said web extends to hold the screwagainst axial movement, but with freedom for vrotary movement. On theouter'end or lhead of' each screw 1S, issecured a crank by which saidscrew may be rotated. The inner ends of the screws 18 work-V throughapertures 21 formed in the end members of the sectional sash stop- 9-andhave screw-threaded engagement with a nut-z block 22 Iintegrally formedwith plates 23, screwedl or otherwise secured to the inner face* ofthewindow frame section 16 By operating the cranks 20, the window framesectionk 16 'may be moved into the adjacent .weight-box .10, asindicated in Fig.- 5'. VV-henthewindow frame section 16 isin normalposition, the-'nut-blocks 22 extend into the' apertures 21and the/plates23 overlap j the joints formed by the window frame secltion 16 andassist` in rigidly holding said sectionin position;

Two-part hangers 24connected by hinge joints, and coi'perating hingelugs 25 are provided for supporting the window'5 sashes 11 and 12from-the movable windowframe section 16, with freedom for horizontalswinging movementp The hangers 241 are arranged inv` a vertically spacedpair for each window sash and set-into'seatsV formed in the window framesection 16, so-that they are flush with the outer face thereof anddonot, in any way, interferefwiththe vertical sliding; movement `of saidsashes. The lower members A"of the hangers 24 are rigid-ly secured tothe windowk frame section 16 by screws and the upper sections thereofarefree to be turned horizontally outward'and held in this position by theformation of the hinge joints. The movable members of the hangers 24 arereduced in transverse width, so yas to clear the sash cords 13 and notinterfere therewith. These movable members of thehangers 24 have formedtherein longitudinal slots- 26,. which terminate at their inner ends inflateral extensions 27. The hingey lugs 25y are integrally formed withhinge plates 28,.setv into the top andbottom` rails ofthe window sashes11 and`12 and rigidly secured thereto by screws. The outer ends of thehinge lugs 25 are bent laterally and transversely ofthe window sashestoformk hooks.

To connect the 4window sashes to the hangers 24the lower sash is firstraised and the movable members ofthe two lower hangers turnedhorizontally outward and said sashes then lowered thereon. This movementof the window sashes willV carry the hinge lugs 25, on their lowerrails, into the slots 27 of the lower hangers 24 and the khooked-ends ofsaid lugs will pass through the lateral extensions of saidy slots. Themovable .sections of the upper hangers 24 are then turned horizontallydownward onto the top rails of the window sashes, which brings the upperhinge lu-gs25 into'the slots of said upper hangers and the hooked endsof said lugs through the lateral extensions of said slots.

With the window sashes thus supported by the hangers 24, the cranks 2Oare operated to move thewindow frame section 16 into the adjacentweight-box 10 a distance suficient to permit the free vertical edges ofthe window sashes to swing horizontally inward by the adjacent sashstops 7 and 9. The sashes are then swung slightly intothe room to clearthe window frame and the cranks 20 again operated to bring the windowframe section 16 back into normal position. The two sashes may be thenswunginto positions, substantially as shown in Fig. lnswinging thesashes into these positions, the hinge lugs 25 thereof work or areforcedlinto the outer extremities of the slots 27 in thev movablemembers of the hangers 24,.which carries their hooked ends o ut ofregistration with ther lateral extensions of said slots, andtherebysecurely'interlocks the hangers 24 and hinge lugs-25.

With the window sashes swung'into the room, as described,'-they may bewashed on the outside, painted or repaired, and then`v returned to theirnormal positions. With the window sashes in this position, it is also anextremely simple matter to paint the window frame from the inside of thebuilding. rflic extra long sash cords 13, attached to the freehorizontal swinging edges'of the window sashes, permit said windowsashesto be swunglhoi'izontally into a room, without 100 detaching thesash cords 13 therefrom, as shown in- Fig. 4.

What I claim is 1. The combination with a window frame having verticalinner, outer and intermediate sash stops, upper and lower window sashesmounted between the sash stops for vertical sliding movement, one sideof the window frame having a movable section, the respectiveintermediate sash stop being sectional with the section thereofextending over the movable sectionof the window frame secured thereto,means detachably connectingl the window sashes to the movable section ofthe window frame for horizontal swinging movement, and means foradjusting the movable section ofthe window frame horizontally to carrythe window sashes into and out of interlocking engagement with oppositesash stops.

2. The combination witha window frame having vertical inner, outer andintermediate sash stops, upper and lower window sashes mounted betweenthe sash vstops for vertical sliding movement, one side of the windowframe having an intermediatemovable section between its inner and outersash stops, the respective intermediate sashv stop being sectional withthe section thereof extending. over the movable section.y of the Windowframe secured thereto, means deframe to carry the Windowsashes into and-10 tachably connecting the Window sash to the out of interlockingengagement With oppomovable section of the Window frame for site sashstops.
